This equation determines the properties of most wave phenomena, not only light waves. In many real-world situations, the velocity of a wave WebJun 19, 2024 · The wave vector is perpendicular to the direction of motion of waves, by definition. Let's say you observe these waves and you'd want to count number of waves per unit length in a particular direction. If you stand on the x -axis, you'd count k x number of waves, and k y if you stand on the y -axis.
